Abstract

The present application is directed to an adhesive article comprising a pressure sensitive adhesive layer and a release layer in contact with the pressure sensitive adhesive layer. The release layer comprises a polyolefin block copolymer. Generally, the polyolefin block copolymer has a density of no greater than 0.9 g/cc.

Description

Release liner
Technical field
The present invention relates to release liner.For example, can be used as the material of the release liner of pressure-sensitive bonding adhesive tape.
Background technology
Stripper surface is for example knowing in pressure-sensitive bonding adhesive tape industry, and the stripper surface providing can make adhesive tape can not make tackiness agent be bonded at the adhesive tape back side from tape roll unwinding.Also release coating can be coated on liner, this liner serves as the carrier of pressure sensitive adhesion transfering belt or double sticky tape, and the two sides of these two kinds of adhesive tapes all has viscosity.Stripper surface also can be used as the release liner for pressure-sensitive adhesive film.
The material that is generally used for stripper surface and coating is silicon composition, because these compositions can be mixed with to provide from " height " and peel off (, very low in order to the power of unwinding adhesive tape) and peel off the various levels of peeling off of (conventionally need larger power carry out unwinding) to " low adhesion gum ".
The main drawback of silicone release coating is possible have associated pollution.In the time that workman operates adhesive tape with silicone release coating or liner, organosilicon can be transferred on their hand, work gloves or clothes.Organosilicon also can be transferred to surface to be sprayed paint from its hand, thereby causes the problem such as paint is nonwetting to the paint that is bonding weak and organosilicon place surf zone of contaminated surface.In addition, electronic device fabricators is not used organosilicon to avoid appearance in manufacturing processed to pollute conventionally.In addition, organosilicon release liner is often more expensive, and is difficult to reclaim with the material of organic silicon coating.In addition, organic silicon coating needs extra operation conventionally, for example, be conventionally coated in existing substrate at second step.Thereby increase manufacturing cost.
Polyethylene has also been used as release liner, and can be coated in and on kraft paper, form release liner, or can be used as unitary film, or can be used as having and the multilayer film of basic unit's coextrusion or laminated polyethylene (such as high density polyethylene(HDPE) etc.).More highdensity polyethylene is only limited in some tackiness agent and uses, and has found that it is not suitable for the pressure sensitive adhesive of extremely strong power, because the bounding force between polyethylene and tackiness agent is very strong, so that is difficult to start the removal to liner.In the time attempting tackiness agent to separate from liner, because peeling force is higher, tackiness agent and/or liner may also can be damaged.
Some polyolefin polymers and atactic polyolefin multipolymer are also used as release liner.In addition, these copolymer blendedly have a polyethylene.Polyethylene is added to and in these polyolefin copolymers, causes producing increase and less desirable peel value.Need a kind of controlled release liner, for not thering is the pressure sensitive adhesive of organosilicon peel ply always.
Summary of the invention
Present patent application relates to a kind of adhesive article, and it comprises pressure sensitive adhesive layer and the peel ply contacting with pressure sensitive adhesive layer.This peel ply comprises polyolefin block copolymer.In general, the density of polyolefin block copolymer is not more than 0.9g/cc.
Embodiment
In present patent application, the material that can be used for peel ply is olefin block copolymers.Suitable alpha-olefin comprises 1-butylene, 1-hexene, 1-octene and their combination.In general, the multipolymer of ethene and 1-octene, as peel ply, is applicable to for example esters of acrylic acid pressure sensitive adhesive.Conventionally these multipolymers are described as to olefin block copolymers.In general, the density of multipolymer is not more than 0.90 gram/cc (g/cc).The density of concrete multipolymer is not more than 0.89g/cc, for example, be not more than 0.88g/cc.In certain embodiments, the density of multipolymer is greater than 0.85g/cc, for example, be greater than 0.86g/cc.This type of olefin block copolymers has also caused reducing gathering and discharging of static in goods, and wherein olefin block copolymers is arranged in the position of contiguous pressure sensitive adhesive.
This multipolymer has high-melting-point conventionally.The fusing point of some multipolymers is approximately 118 ℃ to approximately 122 ℃, for example approximately 120 ℃.
